Insights
Acupuncture may significantly reduce major adverse cardiovascular events (MACE), myocardial infarction, and all-cause mortality in hypertensive patients. This study supports acupuncture as a complementary therapy for hypertension management and cardiovascular disease prevention.
Area of Science:
- Cardiovascular Medicine
- Integrative Medicine
- Hypertension Management
Background:
- Hypertension is a major risk factor for cardiovascular disease.
- Effective management strategies for hypertension are crucial to reduce cardiovascular morbidity and mortality.
- Exploring complementary therapies like acupuncture can offer additional benefits.
Purpose of the Study:
- To investigate the impact of acupuncture on major adverse cardiovascular events (MACE), myocardial infarction, stroke, and death.
- To assess the effectiveness of acupuncture in hypertensive patients receiving anti-hypertensive medications.
- To evaluate acupuncture's role in reducing cardiovascular disease burden.
Main Methods:
- A large cohort of 59,370 hypertensive patients on anti-hypertensives was identified from the Korean NHIS-NSC database (2003-2006).
- Patients were divided into acupuncture and non-acupuncture groups, followed until MACE, myocardial infarction, stroke, or death.
- Propensity score matching (PSM) created comparable groups (18,011 each); hazard ratios (HRs) were calculated using Cox proportional hazard models.
Main Results:
- Acupuncture was associated with significantly lower HRs for MACE (0.83), all-cause mortality (0.73), and myocardial infarction (0.85).
- Acupuncture significantly reduced the risk of stroke-related mortality, ischemic heart disease mortality, and circulatory system disease mortality.
- These findings were robust after propensity score matching, indicating a protective effect of acupuncture.
Conclusions:
- This long-term observational study provides evidence for acupuncture's effectiveness in managing hypertension.
- Acupuncture may play a role in reducing the incidence of major adverse cardiovascular events and mortality in hypertensive patients.
- Acupuncture can be considered a valuable complementary therapy for hypertension and cardiovascular disease prevention.
Objectives:
The aim of this study was to investigate the effects of acupuncture on major adverse cardiovascular events (MACE), myocardial infarction, stroke and death in hypertensive patients taking anti-hypertensives.
Methods:
Using the Korean National Health Insurance Service-National Sample Cohort (NHIS-NSC) database, this study identified 59,370 patients taking anti-hypertensives who had been diagnosed with hypertension between 2003 and 2006. They were divided into acupuncture and non-acupuncture groups. The follow-up period ended with the diagnosis of myocardial infarction, stroke or death. After propensity score matching (PSM), there were 18,011 patients each in the non-acupuncture and acupuncture groups. We calculated the incidence rate, hazard ratio (HR) and 95% confidence interval (CI) for MACE, myocardial infarction, stroke and death in patients with hypertension using a stratified Cox proportional hazard model. In addition, secondary outcome analyses for stroke and cardiovascular mortality were performed.
Results:
After PSM, the HRs for MACE (0.83, 95% CI 0.80-0.86), all-cause mortality (0.73, 95% CI 0.70-0.76) and myocardial infarction (0.85, 95% CI 0.79-0.92) were significantly lower in the acupuncture group than in the non-acupuncture group. Moreover, the HRs for stroke-related mortality, hemorrhage stroke-related mortality, ischemic stroke-related mortality, ischemic heart disease-related mortality and circulatory system disease-related mortality were significantly lower in the acupuncture group than in the non-acupuncture group.
Conclusion:
This observational study with long-term follow-up extends the evidence base in support of the effectiveness of acupuncture for the management of hypertension and potentially reduce the burden of cardiovascular disease.
